there may be two possible errors

1) it may be bcz of the change in the polarities while connecting the circuit

2) the connection may not be tight

What is effect of interchanging the galvanometer and driver cell in meter bridge?

Interchanging the galvanometer and driver cell in a meter bridge would reverse the deflection of the galvanometer. The direction of current through the bridge wire would also change, affecting the balance point. The new balance point will now represent a different ratio of the unknown resistance to the known resistance.


What is steady deflection?

When battery key and galvanometer key are pressed together ..throws comes out on the meter scale which goes on either side and stop there..that is steady deflection...


Why is the lamp and scale arrangement in a ballisitics galvanometer at a distance of 1 meter from the galvanometer?

The lamp and scale arrangement in a ballistic galvanometer is placed at a distance of 1 meter to ensure that the deflection of the galvanometer caused by the current pulse is accurately measured. Placing it at this distance allows for the angular displacement of the galvanometer's coil to be proportional to the charge passing through it, aiding in the precise measurement of the current pulse's magnitude.

What happens to a galvanometer when a magnet is flicked across the coil?

When a magnet is flicked across the coil of a galvanometer, it induces an electric current in the coil due to Faraday's law of electromagnetic induction. This current causes the galvanometer needle to deflect, providing a quantitative measure of the strength and direction of the magnetic field created by the moving magnet.


What is the deflection sensitivity of a cathode ray oscilloscope?

It is the deflection on the screen (meter) per volt of deflection


What kind of meter is created when is shunt is added to a galvanometer?

A galvanometer with a low resistance shunt in parallel makes an ammeter.


What is coil galvanometer meter and its application?

A coil galvanometer is a type of device that uses a movable coil in a magnetic field to measure electric current. As the current flows through the coil, it experiences a torque that causes it to move, with the deflection indicating the strength of the current. These galvanometers are used in applications such as measuring small currents, detecting the presence of current, and in analog meter movements.


What is Ballistic galvanometer Explain its construction?

A Ballistic galvanometer is a type of moving coil galvanometer that is designed to measure the total quantity of charge passed through it. It has a heavy coil suspended by a spiral spring in a magnetic field. When a current is passed through the coil, it moves against the spring and remains in that position, allowing the total charge to be calculated by measuring the angle of deflection.


How do you study earth's magnetic field using a tangent galvanometer?

A tangent galvanometer measures the strength and direction of a magnetic field. To study Earth's magnetic field using a tangent galvanometer, you would need to align the galvanometer with the Earth's magnetic field direction and measure the angle of deflection caused by the field. By analyzing the deflection angle and applying relevant formulas, you can calculate the strength of Earth's magnetic field at that location.


Construction of ohm meter and megger?

Ohm meter is basically a series combination of resistances and galvanometer and source of current .Used to determine unknown resistance.


How do you convert a galvanometer to an ammeter?

To convert a galvanometer to an ammeter, you need to connect a shunt resistor in parallel with the galvanometer. The shunt resistor allows a portion of the current to bypass the galvanometer, ensuring that only a known fraction flows through it. The shunt resistor value can be calculated using the formula Rshunt = (G - 1) * Rg, where G is the desired full-scale deflection of the ammeter and Rg is the internal resistance of the galvanometer.
